Orion Starseeker IV 150mm Telescope Review

Mid-sized telescopes typically have more to offer than their smaller counterparts. Most have larger apertures, which hold several major advantages. Aperture size influences the amount of light drawn in. Therefore a larger aperture means more light. Thus, dimly lit objects further away in space become identifiable. Other inclusive features include computer systems, finders, and databases. Databases provide additional information on thousands of celestial objects. The database acts as an alternative to standard field guides. The computerized finder works great for several reasons. Light pollution makes the process of tracking objects more difficult. Ambient light causes the sky to glow. In turn, dimly lit objects become harder to see. A computerized finder solves this problem. A built-in auto-finding program locates the objects you want to see. Beginners also benefit and learn to correctly identify celestial objects. As a “beginner” mid-sized telescope, both novices and veterans get value out of the Orion 13161 Starseeker IV. The Starseeker IV makes for a great investment for any serious stargazer.


The Orion 13161 Starseeker IV offers a large aperture. The increased size provides improved visibility. Fine details and dimly lit objects are displayed effortlessly. For example, this includes the moons of Jupiter or rings of Saturn. Smaller apertures typically cannot display these finer details. A computerized finder simplifies the process of tracking objects. Beginners and areas with moderate light pollution will greatly benefit. Simply set the finder to a specific object in the sky. The finder will automatically locate the object. Two different sized eyepieces and tripod come included. The 23mm and 10mm optical ability allow magnification for most objects. Forget your field guide at home? No problem, access to a large online database acts as a referencing guide. The database consists of information on thousands of celestial objects. Setting up the Starseeker IV requires very little time. Collimate both eyepieces and you’re set. The Orion 13161 provides long-lasting value. Basic models typically require replacement within several years. The Orion 13161 offers immense value for years to come. The specs and features will benefit beginners and veterans. A long lifespan will ensure years of entertainment and save money in the long term.


The Orion 13161 Starseeker IV requires an external A/C power source. However, this becomes an issue for viewing sessions at remote locations. Without a power source, the telescope does not function. The computer system also quickly drains batteries. For rural locations, additional batteries are a must. When powered down, the computer system completely resets. No option exists to save previous settings. An inconvenience for those who utilize the computer and database. Individuals unfamiliar with technology may find the computer system confusing. The biggest problem with the Orion 13161 revolves around the cost. Pricewise, the Orion 13161 Starseeker IV will leave a dent in your wallet. Alternative beginner telescopes exist on the market for much cheaper. As a mid-sized telescope, the Starseeker IV lacks portability. No bag or carrying case comes included. The accessories and batteries add to the excess weight. Due to the size, transportation requires some planning. Compared to smaller models simply thrown into a “to-go” bag.
